Which file format is commonly used for images on the web?

• A. PNG
• B. JPEG
• C. BMP
• D. GIF

Answer: (B)

The most commonly used file formats for images on the web include PNG and JPEG, but JPEG is particularly prevalent for photographs and images with gradients because of its efficient compression method. This format significantly reduces the file size without sacrificing too much quality, making it ideal for web use where loading speed is essential. JPEG supports millions of colors, allowing for rich and vibrant images, which is why it is favored for photographic content. Additionally, it provides a good balance between image quality and file size, enabling faster loading times and improved user experience on websites. Given its ubiquity in digital photography and online image distribution, JPEG has become a standard for web images, especially those where file size reduction is necessary. While PNG is also a popular format, especially for images requiring transparency and higher color fidelity, it tends to have larger file sizes compared to JPEG, making JPEG the more common choice for general image use on the web. Formats like BMP are rarely used because they tend to be larger and lack compression, which is not practical for web applications. GIF, while widely used for animations and simple graphics, is limited in color support compared to JPEG, particularly for photographs.
